Transceiver CBO QSFP28-100G-CWDM4 BO28L13602D 100G QSFP28 CWDM4 optical module

CBO QSFP28-100G-CWDM4 BO28L13602D is a 100G QSFP28 CWDM4 fiber optic transceiver module designed for high-speed data transmission over single-mode fiber. The module implements four CWDM wavelength lanes to deliver aggregate 100 Gbps capacity in a compact QSFP28 form factor. It is intended for short- to medium-reach optical links in data center interconnects, core and aggregation networks where cost-effective, dense 100G connectivity is required. The transceiver supports standard QSFP28 electrical interfaces and interoperates with compatible QSFP28 ports.

Advantages

The transceiver offers a compact QSFP28 form factor that integrates four independently modulated CWDM lanes, reducing space and power consumption compared with discrete 4x25G solutions. Its single-mode fiber design enables longer link distances than multimode alternatives while maintaining stable signal integrity. Compatibility with standard QSFP28 interfaces simplifies deployment in existing switches and routers that accept QSFP28 modules. The module’s CWDM architecture provides a cost-efficient approach to 100G links by using wavelength-division multiplexing over a single pair of fibers.

Suitable for

• Data center interconnects between racks or pods
• Core and aggregation layer links in campus or service provider networks
• High-bandwidth server uplinks and switch-to-switch connections
• Short- to medium-reach single-mode fiber runs

Key specifications

• Form factor: QSFP28 (quad small form-factor pluggable)
• Aggregate data rate: 100 Gbps (4 × 25 Gbps lanes)
• Optical technology: CWDM (coarse wavelength-division multiplexing)
• Fiber type: single-mode fiber (SMF)
• Typical reach: short- to medium-range single-mode links
• Connector interface: duplex/paired single-mode optical connection compatible with QSFP28 breakout optics
• Electrical interface: QSFP28 compliant electrical signaling

How to use

Insert the QSFP28 transceiver into a compatible QSFP28 port on a switch, router, or network interface card until it clicks into place. Connect the single-mode duplex fiber cable to the transceiver’s optical receptacle, observing correct polarity and recommended connector types. Ensure the host device is configured for a 100G CWDM4 transceiver or set to auto-negotiate where supported. Monitor link status and optical power via the host management interface and verify that the remote end is configured for matching 100G CWDM parameters.
